Binomial distribution is used for discrete random variables with fixed number of trials and constant probability, while Hypergeometric distribution is used for sampling without replacement.

• Binomial distribution is used when there are fixed number of trials, each trial is independent, and the probability of success remains constant.

• Hypergeometric distribution is used when sampling without replacement, where the probability of success changes as each item is selected.

• Binomial d...read more

Z score table is used to find the area under the normal curve corresponding to a specific Z score.

• Look up the Z score in the table to find the corresponding area under the normal curve.

• Z score represents the number of standard deviations a data point is from the mean.

• The Z score table provides the probability of a standard normal random variable being less than the given Z score.

• For example, if Z score is 1.96, the table will show the probability of a standard normal random v...read more
